I have a laptop from PC specialist, which will happily boot in normal mode using the 5.3.0-45 kernel, but won't boot at all in the 5.3.0-46 kernel (not even in recovery mode).
When 5.3.0-46 attempts to start you can see a black screen with the notification area faded; the normal User selection box and password prompt are not visible.
I am not sure what files might help diagnose the issue
